ADJUSTABLE CONNLElG'JTION FOB. SWITCH-POINTS.

Specification of Letters Patent.

Patented Nov. 23, 1915.

Application filed. July 16, 1915. Serial No. 40,285. a

To all whom it may concern f Be it known that I, WILLIAM F. Bossnnr, acitizen of the United States, residing at Utica, in the county of Oneidaand State of New York, have invented certain new and useful Improvementsin Adjustable Connections for Switch-Points; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to the letters and figures of reference marked thereon, which form apart of this specification.

This invention relates to new and useful improvements in switch pointthrowing apparatus for use in connection with railways and consists of asimple and eflicient appa ratus of this nature having various details ofconstruction, combinations and arrangements of parts which will behereinafter fully described, shown in the accompanying drawings and thenspecifically defined in the appended claims.

My invention is illustrated in the accompanying drawings, in which:

Figure 1 is a central sectional View through the boxing forming a partof my improved switch point throwing apparatus. Fig. 2 is an end view,the switch operating bar being in section, and Fig. 3 is a centralsectional View taken in a plane at right angles to the plane of Fig. 1and showing a slight modification in the shape of the nuts and chambersof the boxing.

To illustrate the principle involved in my invention, I have shown aparticular form of apparatus in which numeral 1 designates a boxingprovided with a lateral extension 2 to which the switch throwing bar 3is secured by bolts 4 or any other suitable fastening means. Said boxingis provided with chambered portions 5, the inner ends of which may beflat, convexed or concaved, the latter shape being shown in the drawingsat 5 and 6 designates an opening communicating between the two chambers.

The lower portion of each chamber is elevated as at 7 and its upper edge8 inclines outwardly and downwardly from the inner wall of the chamberedportion.

A switch point throwing rod 10, circumferentially threaded, is movablethrough the boxing and a space intervenes between the circumference ofthe screw and. the, marginal edge of the opening 6 which communicateswith the two chambers. Nuts, designated by numeral 11, are mounted uponthe threaded rod, and their inner ends are adapted to conform to theshape ofthe inner end walls of the chambers. In the form which I havechosen to illustrate, the inner ends of the nuts are shown as beingconvexed and are made preferably on the arc of the same curved surfaceas the inner concaved end of the chamber, so that, when the nut isseated, it will assume the position shown to the right hand end of theboxing, as illustrated in Fig. 1, although it will be understood that Ido not confine myself to this shape as against the outer ends of thenuts 11 and serve to hold the same in their proper adjusted positions.

In Fig. 3 of the drawings, I have shown a boxing 20 which has a lateralextension 21 to which the point throwing bar 22 is held by means ofbolts 23 and the chambered portions 24: of the boxing, instead of beingevenly outlined asillustrated in Fig. 1, are shown as tapering and apassageway 25 communicates between the two chambers of the boxing. Thenuts 26, which are mounted upon the threaded rod 27, are conical-shapedto conform to the tapering walls of the chambers and the inner ends ofthe nuts are convexed and adapted to conform to the con caved inner endof each chamber 24. Jam nuts 28 are fitted to the rod and bear againstthe outer ends of the nut. Said nuts 26 are of suflicient length so thattheir outer ends, when at their inner limits, will project out beyondthe ends of the chamber in which it is located so that a tool may beapplied to the circumference of the nut for the purpose of adjusting thesame.

In the form shown in Fig. 3 of the drawings, it will be noted that theraised surface upon the bottom and which is shown in Fig. 2 is dispensedwith, the walls of the chamher being of a uniform concavity andconforming to the shape of the inner and of the nut and so arrangedthat, when the rod is moved in one direction or the other, the inner endof the nut will seat uniformly about the marginal edge of the openingleading through one chamber to the other,'by the sudden rise of the nutas it moves toward theinner end of'the'chamber, and affording meanswhereby any water whichmay enter the chambers may drain to preventfreezing of the'nuts to'the wall of the chambers.

It will be noted in'the drawings that the chamber is of larger capacitythan the size of the nut which is movable therein in order to allowthe-nut to have a play incident to its being elevated by the inclinedwall of the chamber on the raised portion of the bottom thereof, sothat,when the nut seats, its axis will be in a line with the axis of thechamber, the size of the'chamber providing for the creeping of theswitch points or any bers and passageways, nuts mounted on said rods,and'means for elevating the nuts as they move longitudinally so thattheir longitudinal centers will be in alinement with the, axis of thechamber in which they are located. v V r V '2, An adjustable connectionfor railway switch points comprising a boxing with chambered portionsin, the opposite ends- 7 thereof with a central communicating pasthe rodupon which they are mounted to bring the longitudinal center of the nutin alinement with the axial center of the chamber in which it islocated.

3. An adjustable connection for switch points, comprising a boxingprovided with chambered portions in the opposite ends thereof and acommunicating passageway between the same, a switch point throwing rodpassing through said chambers and passageway, nuts mounted upon saidrods, the lower portions of the chambers upon which the nuts rest beingoutwardly and downwardly inclined and serving as means to raise the nutas it approaches its seat about the marginal edges of said passageway inthe inner ends of the chamber.

4. An adjustable connection for switch points, comprising a boxingprovided with chambered portions in the opposite ends thereof and acommunicating passageway between the same, a switch point throwing rodpassing through said chambers and passageway, nuts mounted upon saidrod, its outer end projecting beyond the outer ends of the boxing, thebottom of each chamber beingoutwardly inclined and upon which the innerportions of the nuts are adapted. to rest, and jam nuts upon the rodengaging said nuts.

In testimony whereof I hereunto aflix my signature inpresence of twowitnesses.
